Energy is ___ changing.
- A.
Always
- B.
Never
- C.
Sometimes
Correct Answer
A. AlwaysExplanation
Energy is always changing because it cannot be created or destroyed, only transformed from one form to another. This is in accordance with the law of conservation of energy, which states that the total amount of energy in a closed system remains constant. Energy can change from potential to kinetic, from mechanical to thermal, from electrical to light, and so on. Therefore, energy is constantly undergoing transformations, making the statement "always" the correct answer.Rate this question:

Energy transformations that involve chemical changes also produce ___.
- A.
Electricity
- B.
Friction
- C.
Radiation
- D.
Heat
- E.
Sound
Correct Answer
D. HeatExplanation
Chemical changes involve the breaking and forming of chemical bonds, which requires energy. During these energy transformations, some of the energy is released as heat. This is because chemical reactions involve the rearrangement of atoms and molecules, which leads to the release or absorption of energy in the form of heat. Therefore, it is expected that energy transformations involving chemical changes would produce heat as a byproduct.Rate this question:

The law of conservation states ___
- A.
Energy can be created and destroyed.
- B.
Energy is never created nor destroyed.
- C.
What goes up must come down.
- D.
Electrical energy can be transformed into other forms.
Correct Answer
B. Energy is never created nor destroyed.Explanation
The correct answer is "Energy is never created nor destroyed." This statement is known as the law of conservation of energy, which is a fundamental principle in physics. According to this law, the total amount of energy in a closed system remains constant over time. Energy can only be transferred or transformed from one form to another, but it cannot be created or destroyed. This principle is based on the observation that energy is a fundamental property of the universe and is always conserved in any physical process.Rate this question:

Where is the potential energy greatest?
- A.
At the dip two cars past the red arrow.
- B.
As the car is moving up the hill 3 cars past the red arrow.
- C.
At the top of the hill before the red arrow.
- D.
There is no example of potential energy.
Correct Answer
C. At the top of the hill before the red arrow.Explanation
The potential energy of an object is greatest at the highest point of its motion. In this case, the highest point is at the top of the hill before the red arrow. At this point, the car has gained the most potential energy due to its elevated position. As the car moves down the hill, the potential energy decreases. Therefore, the correct answer is at the top of the hill before the red arrow.Rate this question:

Where is the kinetic energy GREATEST?
- A.
As the biker is climbing the hill.
- B.
As the biker is at the top of the hill.
- C.
AS the biker is on the downside of the hill.
- D.
There is no example of kinetic energy.
Correct Answer
C. AS the biker is on the downside of the hill.Explanation
The kinetic energy of an object is the energy it possesses due to its motion. Kinetic energy is directly proportional to the mass of the object and the square of its velocity. When the biker is on the downside of the hill, it is moving at a higher speed due to the gravitational pull, which increases its kinetic energy. Therefore, the kinetic energy is greatest when the biker is on the downside of the hill.Rate this question:

During energy transformations, energy is never __________.
- A.
Released as heat
- B.
Used to increase an object's potential energy
- C.
Created or destroyed
- D.
Completely transformed
Correct Answer
C. Created or destroyedExplanation
During energy transformations, energy is never created or destroyed. This is known as the law of conservation of energy, which states that energy cannot be created or destroyed, but it can only be transferred or transformed from one form to another. This principle is based on the understanding that energy is a constant in a closed system, and any energy lost in one form will be gained in another form. Therefore, energy can be converted into different forms such as heat, potential energy, or kinetic energy, but the total amount of energy in the system remains constant.Rate this question:

A __________ is a device that transforms kinetic energy into electrical energy.
- A.
Furnace
- B.
Boiler
- C.
Turbine
- D.
Generator
Correct Answer
D. GeneratorExplanation
A "generator" is a device that transforms kinetic energy into electrical energy. Generators are commonly used in various applications to produce electricity by converting mechanical energy, often in the form of rotational motion (kinetic energy), into electrical energy through the principles of electromagnetic induction. Turbines are machines designed to capture kinetic energy from a moving fluid and convert it into mechanical energy, usually in the form of rotational motion.Rate this question:

A baseball is hit into the air with a bat. When does baseball have the greatest gravitational potential energy?
- A.
When it reaches its highest point
- B.
When the mechanical and kinetic energies of the baseball are equal
- C.
When it leaves the bat
- D.
When it hits the ground
Correct Answer
A. When it reaches its highest pointExplanation
The baseball has the greatest gravitational potential energy when it reaches its highest point. At this point, the baseball is at its maximum height and therefore has the maximum potential energy due to gravity. As the baseball falls back down, its potential energy decreases and is converted into kinetic energy. So, at the highest point, the gravitational potential energy is at its maximum.Rate this question:

_________ is energy stored by things that stretch or compress.
- A.
Elastic potential energy
- B.
Chemical kinetic energy
- C.
Elastic kinetic energy
- D.
Gravitational potential
Correct Answer
A. Elastic potential energyExplanation
Elastic potential energy is the energy stored in objects that stretch or compress. When an object is stretched or compressed, work is done to change its shape, and this work is stored as potential energy. This type of energy is commonly observed in materials like rubber bands or springs, where the energy is stored when they are stretched or compressed and released when they return to their original shape. Chemical kinetic energy refers to the energy associated with the movement of atoms and molecules in a chemical reaction. Elastic kinetic energy is not a recognized form of energy, and gravitational potential energy refers to the energy stored in an object due to its position in a gravitational field.Rate this question:
-
- 14.
What two factors determine how much gravitational potential energy is an object?
- A.
Weight and speed of the object
- B.
Shape of the object and its position relative to the ground
- C.
Weight of the object and height above the ground
- D.
Shape and speed of the object
Correct Answer
C. Weight of the object and height above the groundExplanation
The gravitational potential energy of an object is determined by its weight and height above the ground. Weight refers to the force of gravity acting on the object, while height represents the distance between the object and the ground. As the object's weight or height increases, its gravitational potential energy also increases. The speed and shape of the object do not directly affect its gravitational potential energy.Rate this question:
